At time t = 6.5 sec, a particle of mass M = 1.5 kg is at the position (x,y,z) = (4,4,6) m and has velocity (2,1,-2) m/s.
1) Finally a thin rod of mass 7 kg is added between the two particles Since the particles are moving perpendicular to the line separating them and in opposite directions (you should convince yourself that this is true), then the particles + rod system rotates about its center of mass. What the angular frequency of rotation of the rod + particles system? (Note: The particles are moving perpendicular to the line separating them and in opposite directions (you should convince yourself that this is true), then the particles + rod system rotates about its center of mass.)
2) What is the magnitude of the total angular momentum of the system (particles plus rod)?
